Subject: [PATCH] patchelf: Check ELF endianness before writing new runpath
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
[ upstream commit e88d83c8b4e42a3358a90b781a5a98efa279ff15 ]
This commit modifies the way fields are written in the dynamic
section in order to account the architecture of the target ELF
file. Instead of copying the raw data, use the helper functions
to convert endianness.
